Human adenovirus 5. This is an ultra-thin section of an infected cell in a cell culture. Adenoviruses replicate in the nucleus of cells and as seen here they may reach extraordinary concentrations. When isometric particles are crowded together they form six-fold, three-dimensional arrays—when such arrays are sectioned one sees various planes of section because the pseudocrystalline array is not perfect. Magnification: approximately x80,000.

Human adenovirus 5, colorized. This is the same ultra-thin section of an infected cell in a cell culture as above, only colorized. Adenoviruses replicate in the nucleus of cells and as seen here they may reach extraordinary concentrations. When isometric particles are crowded together they form six-fold, three-dimensional arrays—when such arrays are sectioned one sees various planes of section because the pseudocrystalline array is not perfect. Magnification: approximately x80,000.
